I just bought a 2015 435i x drive and I'm noticing that when I take corners at higher speeds, like off ramps or on ramps to highways there is a quickly repetitive thumping noise that occurs, like there is something in the tread of the tire. It stops when I straighten the wheel out at the end of the ramp. Is this normal because of x drive or is there something going on with the wheels,tires,drive shaft or something else.
